刚刚在浏览美国非洲堇协会网页时发现了一篇关于光线需求的文章。由于之前有很多花友都对非洲堇的灯光照明提出了疑问，所以在此我贴上原文，并附上中文翻译。这段文字讲的非常基础，希望能给大家带来小小的帮助。原文比较啰嗦的地方我会适当简化，如果有翻译不当之处，还请各位海涵！
Light Requirements
光照需求
The amount of light that an African violet receives is important for its health and overall performance. African violets need light for photosynthesis. While photosynthesis is most often associated with a plan’ts green leaves and stems, its most vital function is to convert carbon, hydrogen and oxygen (in the form of carbon dioxide and water) into usable energy called plant carbohydrates.
非洲堇受到的光照强度对于其健康和整体表现来说非常重要。非洲堇进行光合作用需要光照。虽然光合作用常常和植物的绿叶和茎干有关，但其最重要的作用还是将碳，氢，氧（也就是二氧化碳和水）转化为可用的能量－－植物碳水化合物。
If an African violet does not get enough light it will stop flowering and its leaves begin to turn yellow. It is also likely that the African violet which is not getting enough light, will become rangy as it develops elongated leaves and stems.
如果光照不足，非洲堇就会停止开花，叶子变黄，还会陡长。
If you have access to a light meter, the correct luminosity for African violets is 10,000 to 12,000 lux, or about 900 to 1100 foot candles. When selecting a grow light, it is important to make sure it emits light in both the red and
blue spectrums. Red light is essential for African violets to bloom. Blue light is necessary for photosynthesis to occur and, thus, is vital for the development of green leaves and the production of plant carbohydrates.
如果你有光度计，那么最适合非洲堇的光照强度应该是10000－12000勒克斯(照明度的国际单位)／900－1100尺烛光。当您选择人造植物灯时，一定要保证光源同时散发红蓝光谱。红光谱对非洲堇开花至关重要；蓝光谱是植物光合作用所必须的，因此蓝光对于绿叶的成长，以及植物的能量供给来说是必不可少的。
It is important to remember that African violets need at least eight hours of darkness, each day, in order to bloom. While African violets need a sufficient duration of light to produce florigen (flowering hormone), florigen itself does not trigger blooming until it is dark. For this reason, African violets should receive light for no more than 16 hours a day. To properly regulate the duration of light, you may want to consider getting a timer for your grow lights.
切记：如果要让非洲堇开花，必须保证植株每天至少有8小时的黑暗期（非洲堇也要睡觉的 ）。尽管非洲堇需要足够的光照时间才能产生“成花激素”（一种开花荷尔蒙），然而“成花激素”只有到了黑暗期才能开始起作用。因此，非洲堇每天接受光照不能超过16小时。为了更合理地调节光照时间，您可以为人工光源加一个定时插座。
When growing under lights, it is very important to remember to replace the tubes, at least annually. If growing for show, replace your tubes approximately 3 months before the show date.
给非洲堇使用人工光源时，切记每年至少更换灯管一次。如果您要带非洲堇参加展会，请在开展前大约3个月时更换新灯管。

楼主
为什么会这样！），只好顶贴，为此文“发扬光大”作贡献，
话说偶现在的堇缺的就是光线。。等他生根了 要给他点光线~
